CHARGER FOR CERAMIC MATERIALS.

Patented Feb. 9, 1909.

Application filed July 23, 1908. Serial No. 444,974.

To all whom it may concern:

Be it known that I, CHRISTIAN GIELow, subject of the Kin of Prussia, residing at 28 Jakobstrasse, Gor itz, in the Kingdom of Prussia and Empire of Germany, have invented new and useful Im rovements in is, of which the following is a specification. i

For feeding ceramic materials to machines or apparatus stationary hoppers with rotatory ottoms, stationary scrapers and rotatory knives have already been employed, the scrapers and knives being oppositely bent and adapted to push, the materials to the periphery of the revolving bottom for discharging them through openings to without. By means of vertical partitions such hoppers have been divided into several compartments which are to receive different materials, so that after leaving the openings these materials can be collected and sup plied to the respective machine or apparatus. The vertical partitions have been made adjustable for adjusting the proportion of the different compartments. The said hopper presents the defect, that its several compartments require tobe filled with the various, materials from .di'fierent sides, so that the various trucks or wagons containing the materials will have to be moved to the right side by means of sundry tracks, turntables and the like.

My invention relates to improvements in such charging apparatus, whereby the different materials to be charged can be better distributed and their proportion, when once adjusted, can be maintained more exactly than hitherto, and it is rendered possible to charge the several compartments of the hopper with materials of various kinds from one side only, so that a single track will do and the operation. of the hopper or charger is simplified. According to my invention the charger is made turnable around its vertical axis. The openings in its periphery above the revolving bottom are arranged to be more or less opened and closed by means of slides, whereby it is rendered possible to regulate to a nicety the quantities of the difierent materials to be discharged from the charger.

The rotatory bottom is made larger in diameter than the hopper and one or several stationary scrapers are disposed, which form the continuation of one or several of the stationary scrapers within the hopper and are adapted to scrape off from 'the periphery of the rotatory bottom the materials discharged from the hopper through the openings and to conduct them to one or several channels, through which they can be further conducted to the respective machine or apparatus. When only a single stationary external scraper is dis osed, it will collect all the different materia s discharged in the adjusted proportion and deliver them to its channel. When some of the external scrapers are engaged, they can be so arranged as to severally scrape off from the periphery of the rotatory bottom one or two or more different materials discharged from the hopper and to conduct them to their respective channels. Means are provided for normally stopping the turnable hopper and for releasing it so as to permit it to be taken along with the rotatory bottom through a certain angle after which it is stopped, so that the respective compartment or compartments can be charged from the truck or wagon on the sin le track.

f will now roceed to describe my invention with re 'erence to the accompanying drawings, in which Figure 1 is a vertical section through my improved charger in a mode of execution on the line EF in Fig. 2, Fig. 2 is a plan of the same, Fig. 3 is a vertical section through the lower part of the same on the line AB in Fig. 2, and Fig. 4 is a horizontal section through the same on the line CD in Fig. 3.

Similar letters of reference refer to similar parts throughout the several views.

In a frame 7" r of any known construction is secured a horizontal race-ring s, which is shown as made from U-iron. Within the race-ring s a cylindrical hopper a is mounted to turn, while it is supported by several (here four) wheels 25 t, which are mounted to turn on pins fixed on the hopper and to run within the race-ring 8. low closed by a rotatory circular bottom e, which is keyed upon a vertical shaftc and is arranged to be driven in any known manner. In the drawingsfor example a cone pulley h is shown which is driven from without and is adapted to drive the bottom 6 by means of a bevel pinion g and a bevel gearing f on the The hopper a is bebottom. The vertical shaft 0 is ournaled in a foot step d of any known construction and in the nave of a stationary four-armed scra er 0; n i 11 (see Fig. 4), which is fastened on t e inside of the hopper a. The arms "i n i n are bent in one direction and adjoin suitable openings 7c k provided in the periphery of the hopper a above the bottom a. The said arms sweep the bottom a and are adapted to Work together with three known knives b b, which are fastened on the shalt c and are bent in the opposite direction, so that during the rotation of the bottom 0 with the knives b b in the direction of the arrow in Fig. 2 on any knife I; sweeping over the scraper arms i 'n i n they will act together somewhat like a pair of scissors and push the material on the bottom 0 to the periphery oi the hopper (2 towards the respective opening it through which the material can leave the hopper. The openings 7c 761 can be closed with movable slides m m which can be severally adjusted by means of their handles shown, so as to regulate the area of the opening and thereby the quantity of material passing through it to without per unit of time. he bottom 6 is made larger in diameter than the hopper a and its external annul exc ss may be made slightly conical, as shown, it ascending to the periphery. Several adjustable partitions 2 r p of any known construction are disposed within the hopper a, so that the contents of the compartments 10 Q01 20 formed by them can be varied as may be desired. A turn able lock 1; is disposed on the race-ring s and is adapted to engage between two proj ections t or u provided on the upper edge ol' the hopper a on opposite sides l'or preventing the hopper from turning. ll here so pre ferred, the projections o b may be omitted and notches may be provided. in the upper edge of the hopper a, so that the turnable look a can engage into any of these notches.

In the drawings a single external scraper i" is shown as lastened on some structure '3, above a channel 2 and a enged to sweep the external annular portion of the bottom 0 without the hopper a. This external scraper i is shown as forming the contiimatien oi' the arm i of the internal scraper, so that it oirects the material passing through the opening is at once to the channel 2, into which the material is permitted to drop for sliding down to the respective machine or apparatus.

When the slide m facing the channel 2 is alone more or less opened, of course only the material in the compartment to will be permitted to pass through the opening it to the channel 2. When two opposite slides m and. m are more or less opened as shown in Fig. 4, the material in the compartment to will pass through the opening 11: to without and move with the revolving bottom 0 until it strikes the material leaving the compartment to through the opening Zr, when both imitcrials will be together scraped oil l'rom the periphery oi the bottom (a and will .l'all into the channel 2. By adjusting the two slides in and m the proportion of the two materials lalling into the channel 2 can be vaiied, and alter the adjustment this proportion will he maintained heneel'orward. ll hen in addition to the said two slides in and in the slide in on the right in 4 is more or less opened, of course the material contained in the compartment to will be permitted to simultaneously leave the hopper a through two openings 7c. The material passing through the right opening it" will first move with the retating bottom c until it meets the nndei'ia passing l'rein the compartment in through the opening in, when both malciiais will together move with the bottom c until they strike the material leaving the compo; l mcnl to through the upper opening l" in l'ig. -l. whereupon ally the materials are scraped oil and. slide down the channel \l hcn a l the [our slides in m are more or less o'pcned, ol course the three ditlercnt materials cont aincd in the compartments in, w and 11" are simul-- taneously discharged through the tour openings 7t' 70 and together scraped oil by the crt ternal scraper Ol' coups-l the piopnllion ol' the three dilletont materials can be val ied by adjusting the ion: slides 1n an. Who: 0 so prel'erred, a fourth adjustable patiition nniy be disposed in addition to the three p:n"ii tions p p p, so that each ol' the loin compai'tments so formed will have a sepa ate outlet.

In addition to the one external scraper i shown a second one may be disposed, for example so to form the continuation ol' the internal scraper arm n, and may conduct to a second channel similar to which leads to another machine or apparatus. lt is obvious, that in this case one mateiial only will pass from the compartment '7!) lo the channel 2, while either one or two or three di'l'l erent materials will pass to the other channel, one or two or all of the thre remaining slides or in being more or loss opened. In case the second external scraper is disposed opposite to the -first one i. ol course one or two dill'crent materials only can be scraped. oil at a time and permitted to fall into each clnmncl. V here so preferred, three or tour external, scrapers may be disposed for scraping the materia s oil the periphery of the bottom 0 into adjoining channels. .ln this case it is obvious, that by opening and closing the slides m m the inn-- terials from any one or two or three or l'our ditlerent compartments can be directed to any one or more of the channels. ln case only two diilerent materials are to be led to one or several channels, of course a single plain vertical partition. may be employed, which divides the hopper into halves, or two llll adjustable partitions p and p or 12 may be employed, if the contents of the two compartments are to be different in size.

A single track 00 as shown will suffice for comfortably charging the different compartments w w w of the hopper. Assuming the hopper a to occupy its position shown at Fig. 2, it is obvious, that the compartment 10 can be charged from a truck on the track 00 and the compartment to can be charged from another truck on the same track as, the two trucks being pushed together or shifted one after theother, as the case may be. When it is desired to charge the third compartment w, all that is required is to merely turn the lock u out of engagement with the respective projection o and to permit the hopper a to be taken along with the rotating bottom 6, until the lock 'v-is turned back for engaging between the two other projections 0 when the hopper a will stop and its compartment w can be readily charged from a third truck on the track :0.

During the rotation of the shaft 0 the three bent knives b b will cut through the mate-.

rials in the compartments and press portions of them on the bottom e, so that they can be discharged in the manner described above. Any larger stone which may be in the materials will be easily pushed by the knife I) along the oppositely bent internal scraper arm t or n or t or n until it passes through the respective opening 70 or k Such stones are not likely to be jammed.

Obviously the operation of the apparatus I need not be stopped when changing from any one of its compartments to another one to be charged from the track x.

The charger described may be varied without departing from the spirit of my invention.
